Yes, I know that humans technically are nature. But could they survive on what they create and make in test tubes and labs in the future?
Food- cloning animals for food, genetically modified plants, artificial agriculture
creating protein and vitamins in test tubes
Building- artificial substances like fiberglass (fiberglass can still be considered unnatural if it was "created" by humans)
The only thing that they would have is water, sun/moon and of course, energy.
This is for a novel I am writing. It takes place many many many many many years in the future. Basically what I'm asking is: At the peak of our advancement, would humans be able to create everything they need?
Serious answers please. If you're not going to answer my specific questions, don't answer. This is just a general question.
